Mq 3 Alcohol Gas Sensor

This is a sensor that is not only sensitive to alcohol particularly ethanol which is the type of alcohol which is found in wine beer and liquor.

Mq 3 alcohol gas sensor.

This fits your. In this project we will go over how to build an alcohol sensor with an arduino. Mq 3 gas sensor. Mq 3 alcohol sensor circuit built with an arduino.

Fig 4 is shows the typical dependence of the mq 3 on temperature and humidity. Mq3 alcohol gas sensor can detect alcohol gas concentrations anywhere from 200 to 10000 ppm. Rs sensor resistance at various concentrations of gases. This module is made using alcohol gas sensor mq3.

There is a heating system inside the sensor which is made up of aluminum oxide. The grove gas sensor mq3 module is useful for gas leakage detection in home and industry. Mq 3 module is suitable for detecting alcohol benzine ch 4 hexane lpg co sensitive material of mq 3 gas sensor is sno 2 which with lower conductivity in clean air when the target alcohol gas exist the sensor s conductivity is more higher along with the gas concentration rising. Sensor resistance at 0 4mg l of alcohol at different temperatures and humidities.

Brief detail about mq 3 gas sensor. Only 2 left in stock order soon. Sensitive for alcohol ethanol output voltage boosts along with the concentration of the. The mq 3 alcohol gas sensor consists of a total 6 pins including a h b and the other three pins are a h b out of the total 6 pins we use only 4 pins.

Users can convert the change of conductivity to correspond output signal of gas concentration through a simple circuit. The alcohol sensor we will use is the mq 3 sensor. The mq3 gas sensor has a very hight sensitivity to alcohol gas. It is suitable for sensing alcohol gas concentration.

When the target alcohol gas exist the sensor s conductivity gets higher along with the gas concentration rising. Contempo views mq 3 alcohol ethanol gas sensor module pack of 4. Alcohol in the clean air. Sensor resistance at 0 4mg l of alcohol in air at 33 rh and 20 rs.

9 99 free shipping. Due to its high sensitivity and fast response time measurements can be taken as soon as possible. The sensitive material used for this sensor is sno2 whose conductivity is lower in clean air. Mq 2 mq214 detection of methane mq303a.

It is suitable for detecting alcohol benzine ch4 hexane lpg co. It is a low cost semiconductor sensor which can detect the presence of alcohol gases at concentrations from 0 05 mg l to 10 mg l. Mq3 alcohol gas sensor mq3 gas sensor is a very easy to use and very handy sensor. The two pins a h are used for the heating purpose and the other two pins are used for the ground and power.

3 3 out of 5 stars 2 ratings. Make sure this fits by entering your model number. Waveshare mq 3 alcohol ethanol gas sensor module gas detector sensor alcohol detection sensor for raspberry pi by waveshare. The sensitivity of the sensor can be adjusted by using the potentiometer.
